IMPROVEMENT IN GAS-BURNERS FOR HEATING PURPOSES.

Specifiaation forming part of Letters Patent No. 1 65,095, daed June 29, 1875; application filed December 22, 1874.

To all whom it may concern:

Be it known that I, WILLIAM R. HANKs, of

VVellesley, in the county of Norfolk and State of Massachusetts, have invented Improvements in Gas-Burners for Heating Purposes, of which the following is a specification:

My invention relates to improvements in gas-burners for heatingpurposes and consists in a gas-burner having at and within its inclosed base a gas-discharging orifice, and parallel, or nearly so, with such gas-passage, air-supplying passages communicating with the chamber in which the gas is discharged.

In the drawing, Figure l is a section of my invention on an enlarged scale. Fig. 2 is a top view of the plug having the gas and air passages.

The tube of the burner is shown at a. The plug f, provided with a screwthread, is attached to a pipe connected with a reservoir of gas. This plug has acentral passage, d, through which gas passes, and from which it is discharged into the chamber 9 of the tube. At-

- 1n ospheric air is allowed to enter the chamber 9 through the openings 6, arranged about the opening d. The gas flowing from the tube a. of the burner is ignited at h, and forms a hot current, which ascends rapidly, and draws the atmospheric air in through the openings 0, thereby supplying the gas with an additional amount of oxygen, and acting to give the blaze force. The burner may be applied to any purposes where heat is desired.

I am aware that it is not new to supply a burner of this class 'with atmospheric air through lateral openings in the burner made at or near the opening that supplies the burner with gas, and I am aware that an ordinary burner has been covered or surrounded with a large shell almost entirely open at bottom, and air has been admitted about the enlarged base of the shell in great quantities and with such burners, when tipped into or below a horizontal position, the gas flows from and ignites at these air-supplying passages, which is very objectionable and destroys the force of the blaze.

I11 this my improved burner the air-supplying passages e e are substantially parallel with the gas-passage d, and both lead into a chamber, g, closed, except at the end h, where the flame issues. The atmospheric air is drawn, owing to the current produced by the consuming gas, rapidly and with a considerable force into the chamber g, through the openings 6, the air forming a circular blast about the gas, giving it additional impulse, making the flame issuing from the end It very steady and strong; and this burner may be used inany position, for the flame will issue properly when the end his turned up or down, and the gas will not ignite back of the end h.

I claim- The combination of the tube a with the removable end plug f, having a central gaspassage and a series of airpassages encircling the gas-passage, and leading into a chamber, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
